Horace Field Parshall
Horace Field Parshall (9 September 1865–12 December 1932) was an electrical engineer specialising in rotating electrical machines, railway traction, and electrical distribution. Born in America, he worked for General Electric, later moving to the United Kingdom, where he was involved in the installation of a number of electrical schemes, including the Central London Railway and The Lancashire Electric Power Company, becoming a director of both. In Britain, he was financially successful and used his wealth to construct a mansion, ''Penbury Grove'', near Beaconsfield, Buckinghamshire. After the death of his first wife, he became involved in a bigamy case due to an attempt by a married couple to obtain his wealth through a fraudulent marriage. He authored a number of works on electrical engineering, and a book on the genealogy of his branch of the Parshall family including a short autobiography.

Parshall Flume
The Parshall flume is an open channel flow metering device that was developed to measure the flow of surface waters and irrigation flows. The Parshall flume is a fixed hydraulic structure. It is used to measure volumetric flow rate in industrial discharges, municipal sewer lines, and influent/effluent flows in wastewater treatment plants. The Parshall flume accelerates flow through a contraction of both the parallel sidewalls and a drop in the floor at the flume throat. Under free-flow conditions the depth of water at specified location upstream of the flume throat can be converted to a rate of flow. Some states specify the use of Parshall flumes, by law, for certain situations (commonly water rights). The design of the Parshall flume is standardized under ASTM D1941, ISO 9826:1992, and JIS B7553-1993. The flumes are not patented and the discharge tables are not copyright protected. A total of 22 standard sizes of Parshall flumes have been developed, covering flow ranges from 0.0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
